strips the www. off of filtered domains such that both the www and non www versions get filtered out in one swoop

allows users to manually enter domains to filter. This works well if people have links from various subdomain URLs like Every-Town-in-the-Country.Spam-Site.com. Just enter Spam-Site.com and it will filter all of them.

Not sure if this has been mentioned but it would be nice to have url open in a new page or tab. When you click to investigate a site and then come back to link harvester, it can sometimes take a while to reload.

Hi Aron,
because your tools need script DOM en XLM for the yahoo api, your tools will not work under php5.
Do you (or your develop) know of any solutions.
is your site not running gon php5 yet anayway?
